Linus,

Tracing fix for 6.13:

- Fix trace event string check when dealing with array of strings

The xe_bo_move event has a field that indexes into an array of
strings. The TP_fast_assign() added the index into the ring buffer
and the TP_printk() had a "%s" that referenced the array using the
index in the ring buffer. This is a legitimate use of "%s" in
trace events. But this triggered a false positive in the
test_event_printk() at boot saying that the string was dangerous.

Change the check to allow arrays using fields in the ring buffer
as an index to be considered a safe string.


Please pull the latest trace-v6.13-rc5 tree, which can be found at:
